Title: Preparation of dried fish
Inventor: MATSUSHITA YOSHITAKA
IPC: A23L17/00
Filed: 1988-12-20
Abstract: PURPOSE:To obtain a dried fish having large fraction of a deliciousness component and excellent tone of color by broiling a pre-treated raw fish with a heating device such as charcoal fire or far-infrared ray and performing torrefaction. CONSTITUTION:For instance, a filleted bonito is broiled with a heating device efficiently generating charcoal fire or far-infrared ray for about 1 hour. Next, said broiled bonito is repeatedly subjected to torrefaction treatments in a smoke room to afford a dried bonito. By broiling before torrefaction treatment, inner temperature of fish attains 70-90 deg.C and protein is sufficiently modified, thus denaturation of deliciousness, etc., or generation of useless component such as astringency is not yielded even torrefaction is repeated in the smoke room.

Title: Optical scanner
Inventor: AKATSU KAZUHIRO
IPC: B41J2/44
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To make exposure light quantity constant and to change printing line width and printing dot density by controlling light output from a light source so that light outgoing through a slit may be constant even if the width of the slit is changed. SOLUTION: The slit 7 having structure by which beam width in a vertical scanning direction is changed is provided between the light source 1 and a rotary polygon mirror 4, and a motor 7' changing the slit 7 is arranged. When the slit width becomes small in such constitution, the light quantity outgoing from the slit 7 is reduced. For example, assuming that the beam width in the vertical scanning direction is 6mm as a whole in the light beam having uniform distribution, the light quantity outgoing from the slit 7 is reduced as the slit width becomes small. Then, the light quantity of the light source 1 is controlled to be increased as the light quantity is reduced, that is, in accordance with the slit width. Therefore, the light quantity outgoing from the slit 7 is always constant, and the printing line width is changed.  Simultaneously, the printing dot density is changed by changing the revolving speed of the mirror 4 and the modulation clock frequency of the light source 1.

Abstract: PURPOSE:To enhance the reliability of an electrical connection at a through hole by a method wherein a multilayer printed-circuit board is used as one part of an electrode for a plasma discharge operation and a reaction gas is discharged through the hole made in the printed-circuit board. CONSTITUTION:A printed-circuit board 1 is loaded on a transfer jig 2; it is set in such a way that its one part is situated under a plasma discharge tube 9. A reaction gas composed mainly of oxygen gas is emitted from a gas supply port 7 and is discharged from a hole 1a in the board 1; its pressure is adjusted to a definite value; after that, a magnetron 10 is oscillated; a plasma 6 is generated. Due to the generation of the plasma 6, an oxygen molecule or atom which is rich in oxidizing power is generated; while the gas is discharged, the molecule or atom passes through the hole 1a in the printed-circuit board 1 and is moved to a vacuum space 5. A smear inside the hole 1a in the board 1 is oxidized by the passed atom and is removed. After the printed-circuit board has been treated for a definite duration, it is moved, a part which has not yet been treated is treated by an identical procedure. Because the plasma can be generated immediately near the board, the oxygen molecule or atom which is rich in the oxidizing power can be supplied to the board efficiently; a removal speed of the smear inside the hole 1a can be enhanced.
